Sump pump powered by city Water

We have been installing them for a few years, they are a whole lot better than the battery powered ones, and alot cheaper. As long as you have at least 20 psi water pressure they will work just fine. For every gallon used it will pump 2 gallons. Go to www.libertypumps.com
 
Don't need a sump pump. My wife sells them tho. Problem is if town is without power for you to use a regular one then the town will be without power to refill the water tower and if everybody that needed a pump would have them they would be draining the water tower with no water left for fire fighting or other nessary uses and then also the sewage system they are plumbed into would not be able to operate because of no power and would have to dump untreated sewage. A lot of places would not be allowed to have them dump into the roof drain. If you are out in the country and have a spring that would provide the needed constant supply of water for them to operate and then you could dump on top of ground that would be the only good place for them.
 
They are probably an eductor type, I have used them to empty hot tub. It takes a lot more water than they pump, work off vacuum like a carburetor venturi.
 
Like others said,towns have gen.backups.Plumbing supply houses say they sell 20-30 to 1 of those vs.electric ones.But you need a outside water supply to run one.
 
Thank you. I have city water. The town has Diesel Generator to run if we were out of power.
 
Don't have one, wish I did. Any city has backup power/water. Our city water is back online in 5 seconds with engines. There are no restrictions on water use or sewer other than what you'll pay for as in use. They use more gals to pump fewer and do make flowing noise, but who cares?! As long as it keeps you from flooding! I know a young couple that used so little city water that they were below the min. gals for billing. They used one of ththose pumps for normal use! to save electric cuz the water was free at that point. Wasteful? Very! but free.
 
If I was on city water and had a house that relied on its sump pump, I would definitely install one of these as a backup to the electric pump.
 
I put one in our mom's house as an emergency backup pump. It uses a nozzel and venturi to push the water out. They do not have much capacity or pressure, maybe 600 gallons per hour maximum against zero head pressure, only eight feet of head pressure (water column height) is all it takes to completely stop it from pumping. Don't try to pump the sump water up to ground level, it won't. Plumb the outlet into a basement sewer line at basement floor level to keep the lift height as extremely low as possible. It is probably illegal to run sump water into your sanitary sewer, so limit that to true emergencies.

The more water you can supply to the pump the better it works, the mfg recommended a 3/4 supply line. I used a Y hose shutoff and a 3/4 inch heavy duty hose to get water from the washing machine's cold water supply to the pump. It's not the best, but it works when it's needed.
 
The towns around here do not have those generators, should have but do not. Last June when the wind storm went thru they were without power for esential services for about 3 days.
 
My wife sells them, head of plumming section of big box store, an she cannot keep in the electric pumps but there is no demand for the water powered ones. don't know if they even try to keep any in stock. And perhaps if you get to 50,000 people in town they might have the backup generators but the towns of 15,000 or less do not have them and they ask that you limit your water use to esential use. If in emergency situation with no power to town if they would find you using one they could cut your water off so you had nothing to flush the stool.
 
I wasn't talking big box stores,Plumbing supply houses are not box stores.That is Walmart thinging.I know a fair amount of small towns(1000-1500)that have backup power,plus the rural water companys have backup power plus backups on all the booster pumps.Storm water isn't treated and you can't dump storm water into a sewage line anyway.
 
This is Lowes and it is the onlu home improvement store in town. And the storm and sanitary are all hooked together, supposed to in the next 20 years to get them seperated, town of about 12,000. All the neighboring towns do not have any backup generators. Should have but do not.
 
As far as numbers sold,Electric over water powered,10,000 to 1 who knows,but on backups maybe even there IF you have way to power them.Batterys go bad or only good for a few hours,but the ram powered ones are almost all plumber installed.A few towns still are working on the sewage seperation,but almost all(small towns) have been since early 60s and EPA runs smoke test every 5-10 yrs.
 
I have a water back up sump pump for when my power goes out. It doesn"t pump as much as my electric, but it keeps my basement from flooding. The float valve to turn on the water back up is about 6" higher in my pump basin than the electric and it easily pumps the 8" high and about 80"run to get the water away from the house.
